C. E. Jones & Shantanu Basu, The Intrinsic Shapes of Molecular Cloud Fragments over a Range of Length Scales, paper with colored figures , or paper with gray-scale figures . This paper is published in ApJ April 10, 2002, 569, 280. (If you are printing in black and white, retrieve the paper with the gray-scale figures so that there are no ambiguities with the color scale in the shaded graphs.)

C. E. Jones, Shantanu Basu, & John Dubinski, Intrinsic Shapes of Molecular Cloud Cores. In this paper we investigate axisymmetric oblate and prolate molecular cloud cores via an analytical method. We show that both oblate and prolate axisymmetric cores lead to results which are unphysical. We demonstrate statistically, that intrinsic triaxial cores produce projected distributions which compare well with observations. This paper is published in ApJ 2001, 551:387.

C. E. Millar, T. A. A. Sigut & J. M. Marlborough, The Continuum Re-processing Efficiency of Be Star Circumstellar Disks, MNRAS 2000, 312,465. We have calculated the total flux emitted in H alpha, P alpha, and Br alpha by the circumstellar envelope of both an early Be star, gamma Cas, and a late Be star, 1 Delphini, assuming the central star is the only source of energy input into the circumstellar envelope. We find that an additional source of ionizing photons is not necessary to account for the observed emission.

C. E. Millar, T. A. A. Sigut, and J. M. Marlborough, Rates of Energy Gain and Loss in the Circumstellar Envelopes of Be Stars . In this article, we demonstrate that a single central B star produces sufficient photoionizing radiation to fully account for observed Halpha fluxes. This is in disagreement with the results of K. M. V. Apparao, Be Star Newsletter, Vol 33, who argues that an additional source of photoionizing radiation is necessary for the later type Be stars. Our article appears in the current issue of the Be Star Newsletter, Vol 34.
